Vomiting is the most frequently encountered complication of CPR.
If the victim starts to vomit, turn the head to the side and try to sweep out or wipe off
the vomit. Continue with CPR.

The spread of infection from the victim to the rescuer is
exceedingly rare. Most cardiac arrests occur in people's homes - relatives or friends will
be the ones needing to do CPR. Even CPR performed on strangers has an exceedingly rare
risk of infection. There is NO documentation of HIV or AIDS ever being transmitted
via CPR.
